Does narrow row spacing punish maize grain yield? The use of narrow row spacing for the different landscape positions of a field could punish maize ( Zea mays L.) grain yield. Two experiments were conducted (2006/07 and 2007/08) at different landscape positions in the Inland Pampas of Argentina.

Does row spacing affect soil water content in maize crops? Differences among row spacings only were significant at R 6 of maize crops at the foot-slope position (, for landscape position x row spacing interaction), where maize cultivated with the skip-row pattern exhibited lower soil water content (~415 mm) than those in narrow rows (~564 and 606 mm for 0.38 m and 0.52 m, resp.).

What is the recommended row spacing for my plants? Appropriate row spacing makes more efficient use of light leading to faster canopy establishment, thus reducing soil moisture evaporation and weed growth. Highland market, Medium altitude wet and medium altitude moist, the recommended spacing is 75 x 25 cm (50,000 plants per Hectare) one seed per hole.

Does soil disturbance affect the yields of maize? At Viljoenskroon, planting maize under minimal soil disturbance resulted in superior yields regardless of the row spacing and plant density ( Graph 3b ). Grain yields were comparable only with maize planted at the narrower spaced rows (0,52 m) with a plant population of 60 000 plants/ha.

Does narrow row spacing punish maize grain yield?

Does row spacing affect maize grain yield in sandy fields? Grain yield reductions (6 to 20%) were detected when crops were cultivated in the narrowest row spacing (rows 0.38 m apart) at the different landscape positions. The hypothesis that the use of the same row spacing for the different landscape positions of sandy fields could punish maize grain yield was tested.

How far apart do you plant crops to improve yield? Grain yield reductions (6 to 20%) were recorded when crops were cultivated in rows 0.38 m apart. The skip-row pattern did not improve grain yield. Maize grain yield was optimized in rows 0.52 m apart along the sandy landscape positions of the fields.

How does kernel number/m2 affect grain yield at landscape positions? Differences in grain yield among landscape positions (mean 806, 893, and 1104 g/m 2 at the summit, shoulder-slope position, and foot-slope position, resp.) were related to kernel number/m 2 ( ), which was closely related () to light capture around silking.

Does row spacing reduction affect maize canopy size? Previous studies documented that row spacing reduction did not modify maize canopy size (i.e. leaf area index); but increased maximum fIPAR and grain yield at low plant densities (~40–65.000 plants/ha) [ 15, 16] or at high plant densities (>75.000 plants/ha) but with low soil resources that affected canopy size [ 9, 10 ].
